Lateral load capacity

[efrenfranco]

I have a project of 3 basement + ground floor + 7 typical floors
the basement is at 15 meter depth i put my pile foundation at 21 meter from EGS. Total length of pile is 6 meter. I need the lateral load for this using Brinch metehod at 0.5 m pile diamter and 0.6 meter pile diameter. can anyone give me some sample coputation for this prblem.

UCS value = 13.1 kg/cm2

soil profile from 15 - 21 meter is rock composed of mudstone

I have never heard of the Brinch method,


Just for curiosity, Why does is it need to be necessarily using that method?

Hansen method is one of many methods available to analyze laterally loaded piers and piles. We use Lateral Foundation (

)

Your structure is multistory and hand methods should be verified by computer output. Also if this is your first time analyzing lateral loads, this is too complex a project-seek an experienced engineer's advice.

if you are using Brinch-Hansen's method you'd need to know the type of soil in the passive zone of the laterally-loaded pile. For long-term performance, this is typically the friction angle. B-H defines the term "C," which is the ratio "kq/kp(rankine). Kq being the passive pressure (per unit area) acting on the pile (this is without any performance criteria - i.e., P-Y response).

In the big scheme of things, you can approximate "C" by the value phi/10 where the value of C is never less than unity. Bear in mind the use of Cp requires that the pile-to-pile spacing in plan dimension is at least 3B, but should really be at least "C"B so you don't overstress the plane strain condition.

What is the soil profile above the lowest basement? The lateral resistance required by the piles could be moot if resistance is already achieved in the 15 metres of basement walls.
